T 0 all whom it may concern:

Be it known that I, KoNRAD MALOHER, a citizen of the German Empire, andresiding at Gleiwitz, Silesia, German Empire, have invented a new anduseful Improved Tipping Truck, of which the following is a description.

The present invention relates to that class of trucks known as tippingor dumping trucks in which the body of the truck is adapted to be tippedon the under frame to empty the contents of the truck at the side of thetrack and the object of the invention is to provide simple means fortipping a truck of comparatively great capacity. In order to attain thisobject the body of the truck is advantageously of rectangular form andboth body and underframe are designed to allow the body to be firstturned horizontally on the frame to the extent of about 90 and thentipped endwise to one side or the other of the track, so that one endboa-rd or door of the body being removed the whole contents of the truckwill be projected out at the side of the track.

In the accompanying drawing forming part of the present specification,Figure 1 is a side elevation of one form of the truck showing the underframe in vertical section, Fig. 2 is a plan view of the under frame,Fig. 3 is an end view of the truck, Fig. 41 a similar view partly insection showing the body in the tipped position and Fig. 5 a view, seenfrom underneath of the body of the truck.

The body a of the truck is advantageously of rectangular shape and isprovided with removable end walls secured in any well known manner. Itmay also be provided with doors in the sides, as illustrated in Fig. 1,for purposes of loading from the side. A plate I) is secured to thebottom of the body a, having a crown of downwardly projecting teeth ithereon and being provided with a central downwardly extending pin 0adapted to engage a corresponding orifice or recess in a longitudinalgirder or beam cl, on which the truck body is advantageously supportedon a set of ball bearings 65. The underframe of the truck consists ofthe two end frames 9, g of a breadth about equal to that of the body aand having suitable bearings for the axles and wheels of the trucks, anda pair of longitudinals h, h to connect up the said end frames. Theselongitudinals are kept comparatively close the said shaft 76' a wormwheel Z is mounted.

with which a worm m on a transverse shaft n engages, the said transverseshaft 11. being also mounted in the end frame 9 and having its endssquared or otherwise suitably formed to receive a crank handle by meansof which the shaft may be turned to rotate the pinion 75 at the body ofthe truck on the underframe, in a horizontal plane.

The two ends of the longitudinal beam (Z are formed to trunnions c, efitting sockets f, f one on each end frame g, g. The said beam d isfurthermore provided with toothed segments 0, 0 keyed thereto and withwhich engage pinions p, 79 mounted on a shaft q, supported in suitablebearings, in a longitudinal direction in the underframe. A worm wheel ismounted at the outer end of the said shaft g, which wheel engages a worm8 formed on a shaft 6 mounted transversely in the underframe and havingits ends squared or otherwise formed to receive a hand crank lever bymeans of which the shaft may be rotated. The truck is manipulated in thefollowing manner When it is desired to tip the body of the truck toempty the same a crank handle is applied to one or both ends of theshaft 11., the pinion 7c is rotated by means of the worm gearing m, Zand the body of the truck is swung around by means of the crown of teeth71, in which the pinion engages, to the extent of about 90 or at anyrate far enough to bring the sides of the body clear of the end framesg, g. Then crank handles are applied to the shaft 6 and the latter isturned so as to rotate the beam 02 on its trunnions e, c by means of theworm gearing 1', s, the toothed segments 0, 0 and the pinions p, 79. Bythis means, the body of the truck may be tipped endwise to either sideof the track, according to the direction in which the shaft 2% isturned, as will be readily understood.

In order vto facilitate the movement of the body a of the truck in thehorizontal plane, rails or tracks u, u may be provided on the end frames9, g and suitable rolls (not shown) may be mounted underneath the bodyof the truck.

The employment of the worm gearing for both movements of the truck bodyobviates the necessity of any arresting devices, since the truck bodywill remain in any desired position, immediately the rotation of theshaft in question a or t is stopped.

The truck may also be tipped for loading purposes, for very heavy goods,in cases where no goods loading platform is provided, the goods beingslid up the inclined bottom of the truck and the latter then readjustedin position on the underframe.

I claim as my invention 1. A tip truck comprising an underframe having apair of wheels at each end, a beam pivotally supported longitudinallyintermediately of the said pairs of wheels, a truck body movablysupported on said frame and a vertical pivotal connection between thesaid body and the said beam, means for rotating said truck on said pivotconsisting of a crown of downwardly extending teeth mounted on thebottom of said body and a driving pinion in engagement therewith mountedon said underframe and means for tipping the said body endwiseintermediately of the wheel pairs substantially as described.

2. A tip truck comprising an underframe for the wheels and a truck bodymovably mounted thereon, said underframe consisting of two wheelsupporting end frames and an intermediate frame portion narrower thanthe said end frames and adapted to connect the same rigidly together, abeam having end trunnions pivotally supported longitudinally in the saidunderframe, a downwardly extending pivot on the said truck bodysupported in the said beam and means for rotating said body on-its pivotand said beam on its trunnions substantially as described.

3. A tip truck comprising an underframe to carry the wheels and a truckbody mov ably supported thereon, a crown of downwardly extending teethon .the bottom of said body and a central downwardly extending pivot onthe same, a shaft mounted in the said underframe having a pinion toengage said crown of teeth, shaft and worm gearing to rotate said pinionshaft, a beam pivoted longitudinally in the underframe in which saidtruck body pivot engages and means for turning said beam on its pivotafter the said body has been swung around horizontally on its pivot.

4. A tip truck comprising an underframe to carry the wheels and a truckbody movably supported thereon, a crown of downwardly extending teeth onthe bottom of said body and a central downwardly ex-V tending pivot onthe same, a shaft mounted in the said underframe having a pinion toengage said crown of teeth, shaft and worm gearing to rotate said pinionshaft, a beam pivoted longitudinally in the underframe in which saidtruck body pivot engages, toothed segments fast on said beam, a shaftmounted in the underframe beneath said beam and pinions thereon engagingsaid segments, and shafting and worm gearing supported in saidunderframe, to rotate said pinions in either direction substantially asdescribed.

In testimony whereof I aflix my signature Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,Washington, D. G.
